Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

The embodiment discloses a dust collector head capable of effectively preventing a rolling brush from being entangled with hairs and a dust collector comprising the dust collector head. As shown in fig. 1 to 4, the head of the cleaner includes a roll brush 1, a holder 2 for mounting the roll brush 1, and a protective cover 4 covering an upper portion of the roll brush 1. As shown in fig. 2, both ends of the roll brush 1 are respectively mounted on the bracket 2 as can be seen after the protective cover 4 is removed. Specifically, the support 2 comprises a left cover plate and a right cover plate, wherein rolling brush installation parts 24 are arranged on the inner side surfaces of the left cover plate and the right cover plate, and rotating shafts of the rolling brushes 1 are installed on the rolling brush installation parts 24. The inner side surfaces of the left cover plate and the right cover plate are also provided with flanges 21, the flanges 21 are cylindrical, the extending direction of the flanges 21 is basically vertical to the plane of the left cover plate or the right cover plate and faces the rolling brush 1, and the rolling brush mounting part 24 is positioned in the area surrounded by the flanges 21. The flanging 21 is at least partially coated on the end head of the rolling brush 1 or inserted into the cylindrical rolling brush 1, and the flanging 21 is in interference fit with the rolling brush 1. It should be noted that, because the material of the rolling brush 1 has a large deformation capability, and part of the product surface has dense bristles, the interference fit only causes a certain deformation of the inner surface or the outer surface of the rolling brush 1, and does not cause the rolling brush 1 to be unable to rotate due to the tight fit.

The flanging 21 is shielded on the end of the rolling brush 1, so that objects such as hair and the like can be effectively prevented from entering the rolling brush 1 from the end of the cylindrical rolling brush 1, the problem that the rotating shaft or other transmission parts of the rolling brush 1 are entangled is solved, the structure is simple, and the processing cost is low.

On the basis of the structure, the flange 21 is provided with a bump 22, and when the flange 21 at least partially covers the end of the rolling brush 1, the bump 22 is attached to the outer surface of the rolling brush 1; when the flanging 21 is at least partially inserted into the cylindrical rolling brush 1, the lug 22 is attached to the inner wall of the brush cylinder of the rolling brush 1, and the lug 22 and the rolling brush 1 are in the two relative position relations, so that the rolling brush 1 can rotate relative to the lug 22. The bump 22 is used for poking foreign matters such as hairs wound on the rolling brush 1, so that the foreign matters fall off from the rolling brush 1, or at least blocking the trend that the foreign matters move to the end part of the rolling brush 1, thereby reducing the probability that the foreign matters move to the end part along the rolling brush 1 and then are wound on the rotating shaft of the rolling brush 1.

The specific structure of the bump 22 is not limited, and the bump can effectively stir the hair and other foreign matters. Preferably, the protrusion 22 has a quadrilateral structure, a bottom side is connected to the flange 21, a top side is far away from the flange 21, two side edges are arranged between the bottom side and the top side, and the linear shape and the inclination angle of the two side edges can be the same or different.

The projection 22 is stationary with respect to the whole cleaner, but the rolling brush 1 and the projection 22 rotate relatively, so that the two sides are respectively located at the front side and the rear side of the relative rotation, the side at the front side is the first side 221, or the first side 221 can also be described as the side located at the upstream side of the rotation direction of the rolling brush 1. In order to achieve a better hair poking effect, the first side 221 is inclined relative to the plane of the left cover plate or the right cover plate, and the other side can be perpendicular to the plane of the left cover plate or the right cover plate.

Preferably, the first side 221 extends in the rotation direction of the roller brush 1 from the bottom edge to the top edge of the protrusion 22. That is, assuming that a line parallel to the axis of the roller brush 1 is drawn on the roller brush 1, and the line is located outside the range covered by the projection 22, the point on the first side 221 closer to the bottom side reaches the drawing line first when the roller brush 1 rotates. In operation, the rolling brush 1 rotates, the first side 221 slides across the outer surface or inner wall of the rolling brush 1, the root of the first side 221 (the portion of the first side 221 connected to the bottom edge) lifts the hairs closest to the end of the rolling brush 1, then the other points on the first side 221 sequentially slide across the area of the rolling brush 1, and the hairs lifted previously are pushed to the middle of the rolling brush 1 by the first side 221, so as to prevent the hairs from winding around the rotating shaft of the rolling brush 1.

To further enhance the plucking effect, the first side 221 may be designed to be wedge-shaped. The first side 221 is very thin at the contact part with the hair, the thin part represents sharp, the side 221 is made into an inclined plane and has the function of cutting off the hair, so the inclined plane is formed, and the hair can be ensured to be stripped from the rolling brush 1; with the rotation of the rolling brush 1, other parts on the first side 221 sequentially reach the positions of the hairs, and the structure of the first side 221 at the positions becomes thicker and thicker, so that the hairs are tilted to a certain height, the suction force or the adhesion force between the hairs and the rolling brush 1 is reduced, and the hairs and the rolling brush 1 are thoroughly peeled off.

As shown in fig. 4, the flange 21 may be formed with a notch 23, the notch 23 being aligned with a surface to be cleaned (e.g., a floor). When the flanging 21 is coated on the end head of the rolling brush 1, the gap 23 ensures that the rolling brush 1 can be completely contacted with the surface to be cleaned, thereby improving the cleaning efficiency; when the flanging 21 is inserted into the cylindrical rolling brush 1, the gap 23 can slightly reduce the circumference of the flanging 21, so that the difficulty of sleeving the flanging 21 on the rolling brush 1 is reduced, in addition, the gap 23 can expose hairs accidentally drilled from the end of the rolling brush 1, and then the hairs are lifted and stirred by utilizing the part of the flanging 21 beside the gap 23, so that the hairs are prevented from being wound on the rotating shaft of the rolling brush 1.

On the basis of the structure, the head of the dust collector also comprises a knife brush, the knife brush comprises a brush rod 31 and a plurality of comb teeth 32 which are sequentially arranged on the brush rod 31, and the brush rod 31 is parallel to the axis of the rolling brush 1. The existing dust collector is also provided with a knife brush, but the teeth of the existing knife brush are all in a sawtooth shape (triangular tooth sheets are connected in sequence), so that the hair removing capability is poor, and the hair can be easily separated from the teeth; the teeth spacing is small, the space for accommodating hairs is small, and once there are many hairs, it is difficult to thoroughly remove them.

In order to solve this problem, the comb teeth 32 in the present embodiment are formed in a sheet shape and are arranged in a direction perpendicular to the axis of the roll brush 1, and a gap for accommodating hair is formed between two adjacent comb teeth 32. The standing sheet-shaped structure can be better abutted against the outer surface of the rolling brush 1 and is slightly pressed into the outer surface of the rolling brush 1, so that foreign matters such as hairs on the rolling brush 1 can be hooked; the gap between two adjacent comb teeth 32 is large, and both ends of the hooked hair can be accommodated in the gap, so that a large amount of hair can be cleaned at one time.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
